I followed Jon's L. tutorial http://www.killerphp.com/zend-framework/videos/zend-development-part-2.php When I opened up Eclipse I have the following folders - html, library, and public.... On the library folder there is a very small "!" mark that indicates warnings. The following is the Description from Eclipse: "!" Warnings (100 of 486 items) "!" No grammar constraints (DTD or XML schema) detected for the document. | Resource - "OpenTypeHistory.xml" | Path - "phpsandbox/.metadata/.plugins/org.eclipse.wst.jsdt.ui" ***I refuse to write the next 99 items that have "!" warnings just use your imagination ***** I'm new to programming and to PHP, ZendFramework, and Eclipse.... I'm currently working on the latest Mac OS. What do I do about the "!"(warnings)?? I know I'm so close I can almost see the light. Thanks
